The Marblehead Merchants Association is holding their first "Monster Mash" event. Shop owners will be dressed in costume and passing out Halloween treats from 11 a.m. to 5 p.m. on Saturday, Oct 26, at the participating shops of Marblehead. It is also the first dinner event of the season at Avery’s Café. Many locations will be offering specials and other event surprises. It's just a short walk through downtown for the kids to collect their “booty”.
